I am trying to fetch comments from Facebook and trying reply that from the application using the access token again a facebook id.
When I am using that from one location continuously it works well even on dynamic IP of my system for days .. but when I tries to use the same at my home.. it is working for 2 times hardly and then blocks the ID... please help me resolve this.
Code here :
string AccessToken = "Acess token here";
GET_POST_LINK posts;
string url = "https://graph.facebook.com/v2.11/mefields=posts%7Bmessage%2Cpermalink_url%7D&access_token=" + AccessToken + "";
HttpWebRequest feedRequest = (HttpWebRequest)WebRequest.Create(url);
feedRequest.Method = "GET";
feedRequest.Accept = "application/json";
feedRequest.ContentType = "application/json; charset=utf-8";
WebResponse feedResponse = (HttpWebResponse)feedRequest.GetResponse();
using (feedResponse)
{
using (var reader = new StreamReader(feedResponse.GetResponseStream()))
{
posts = JsonConvert.DeserializeObject<GET_POST_LINK>(reader.ReadToEnd());
int count = posts.posts.data.Count;
}
}

I'm struggling to connect to the Facebook Messenger API. The server keeps returning:
The remote server returned an error: (400) Bad Request.
I've been at this for a few days, tried multiple methods, even tried a few VS packages that don't quite work. I've checked my Auth Token several times, and I don't know what else it might be.
Is there something obvious that's causing a bad request? I've copied the root URL from Facebook's API page. The token in the code below has been removed. The application throws an exception when I attempt to read the response. (WebResponse FBresponse = FBrequest.GetResponse();)
private string FBSendMessage(string user, string message)
{
string result = null;
string FBroot = "https://graph.facebook.com/v2.6/me/messages?access_token=";
string token = "EAA...DZD";
string FBURI = FBroot + token;
string FBstring = "{ \"recipient\": { \"id\":\"" + user + "\" }, \"message\": { \"text\":\"" + message + "\" } }";
try
{
//using (WebClient FBclient = new WebClient())
//{
// result =
// FBclient.UploadString(FBURI, FBstring);
//}
HttpWebRequest FBrequest = (HttpWebRequest)WebRequest.Create(FBURI);
FBrequest.Credentials = CredentialCache.DefaultCredentials;
FBrequest.ProtocolVersion = HttpVersion.Version11;
FBrequest.Method = "POST";
FBrequest.ContentType = "application/json";
byte[] FBbytes = Encoding.UTF8.GetBytes(FBstring);
FBrequest.ContentLength = FBbytes.Length;
Stream FBstream = FBrequest.GetRequestStream();
FBstream.Write(FBbytes, 0, FBbytes.Length);
FBstream.Close();
WebResponse FBresponse = FBrequest.GetResponse();
Output((((HttpWebResponse)FBresponse).StatusDescription), Log.Error);
FBstream = FBresponse.GetResponseStream();
StreamReader FBreader = new StreamReader(FBstream);
result = FBreader.ReadToEnd();
FBreader.Close();
FBresponse.Close();
}
catch(Exception ex)
{
Output(ex.Message, Log.Error);
}
return result;
}
I have determined that my code isn't the issue. The issue is that I'm making a request with an invalid user id. Facebook creates a user ID in the application context that isn't the same as your default user id. I have to receive a message to learn that contextualized id before I can send a message.
I have a problem when trying to post on my own business time line on facebook.
I get an error that says:
"(OAuthException)(#200) The user hasn't authorized the application to perform this action"
I think this has to do with the scope "publish_actions" in somehow but how can I authorize this publish_actions permission exactly?
I have looked everywhere in my account under "https://developers.facebook.com"
I have put my App for review but I cant add "publish_actions" as a permission for Facebook to review because on this permission there is a message which says: "It looks like you haven't made any API requests to access content with the publish_actions permission in the last 30 days"
But how can I use this permission without having the permission??
I would be very greatful for help if I am on the right track and what I am missing out?
Thank you!
try
{
String appID = "12345";
String appSecret = "123456";
String accessToken = "123|1234_a-b";
String clientToken = "1234567";
String pageID = "123456789";
Facebook.FacebookClient client = new Facebook.FacebookClient(accessToken);

var publishResponse = client.Post("/" + pageID + "/feed", dicParams);
MessageBox.Show("You posted on the timeline successfully!");
}
catch (Exception ex)
{ MessageBox.Show(ex.ToString()); }
Attempt 2:
I was looking at the facebook documentation and found an URL which seems relevant to post a message on the business page timeline:
POST graph.facebook.com/{user-id}/feed?message={message}&access_token={access-token}
I have tried to put it down in code like below but again, I receive the same error message:
(OAuthException)(#200) The user hasn't authorized the application to perform this action
Question is what I do wrong. Do I need to get any other access token with "publish_action" permission?. If that is the case I can't figure out how to get such token?
String appID = "12345";
String appSecret = "123456";
String accessToken = "123|1234_a-b";
String clientToken = "1234567";
String pageID = "123456789";
String message = "Hello World";
String requestUrl = "https://graph.facebook.com/" + pageID + "/feed?message=" + message + "&access_token=" + accessToken;
RestSharp.RestClient rc = new RestSharp.RestClient();
RestSharp.RestRequest request = new RestSharp.RestRequest(requestUrl, RestSharp.Method.POST);
request.AddHeader("Content-Type", "application/json");
request.AddHeader("x-li-format", "json");
request.RequestFormat = RestSharp.DataFormat.Json;
RestSharp.RestResponse restResponse = (RestSharp.RestResponse)rc.Execute(request);
RestSharp.ResponseStatus responseStatus = restResponse.ResponseStatus;
//"(OAuthException)(#200) The user hasn't authorized the application to perform this action"
MessageBox.Show(restResponse.Content.ToString());
I have found a solution which works. This code do post a "Message" to the timeline.
Question This code works for my business page. I also like to post on my personal page for friends. So tried to change the pageID to the the ID which is my personal page: (pageID = "987654321") but still it posts on my business page.
I wonder if I need to get a page token specifically for the personal page as well?
If that is the case, I wonder how this token can be achieved?
/*********************************************************************************************************************************************************************/
//STEPS!!! to get a non-expiring page access token:
//1. access the following URL and note the returned access token within the browser's address bar:
//https://www.facebook.com/dialog/oauth?client_id=APP_ID&redirect_uri=REDIRECT_URI&scope=manage_pages,publish_actions&response_type=token
//2. access the following URL and within the returned data find the desired page's name and note the access token:
//https://graph.facebook.com/me/accounts?access_token=ACCESS_TOKEN_RETURNED_FROM_STEP_1
//3. access the following URL and note the returned access token:
//https://graph.facebook.com/oauth/access_token?client_id=APP_ID&client_secret=APP_SECRET&grant_type=fb_exchange_token&fb_exchange_token=PAGES_ACCESS_TOKEN_FROM_STEP_2

I have facebook integrated on my login page, and now I'm trying to call a build-in action: books.rates using a Test App.
My app gets a valid access_token, and creates new feed items without problems. But when I'm tryng to make a books.rates API call, only works if the logged user is a real person (in my tests is me, also the App administrator), and fails allways with Error 400 when I try to rate a book with a Test User.
In both cases, the code is the same (only access_token and userid changes) and has "publish_actions" premission enabled. I think I'm missing something on Test App configuration, but I'm really lost right now.
Thanks!
Update 1
This is the code that makes the action. It's a test code so its very basic
Dictionary<string, string> postInfo = new Dictionary<string, string>();
postInfo["book"] = "http://www.whakoom.com/comics/6jMl7/52/4";
postInfo["rating:value"] = "4";
postInfo["rating:scale"] = "5";
postInfo["fb:explicitly_shared"] = "true";
string graphUrl = string.Format("https://graph.facebook.com/v2.1/{0}/books.rates?access_token={1}", FbUserID, FbAccessToken);
string fbResp = PostPageContent(graphUrl, postInfo);
private static string PostPageContent(string url, Dictionary<string,string> postData)
{
string postInfo = string.Empty;
foreach(string key in postData.Keys)
{
if (postInfo.Length > 0)
postInfo += "&";
postInfo += string.Format("{0}={1}", HttpContext.Current.Server.UrlEncode(key), HttpContext.Current.Server.UrlEncode(postData[key]));
}
var request = WebRequest.Create(url);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postInfo.Length;
StreamWriter streamOut = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(postInfo);
streamOut.Close();
string retValue = string.Empty;
WebResponse response = request.GetResponse();
var reader = new StreamReader(response.GetResponseStream());
retValue = reader.ReadToEnd();
reader.Close();
return retValue;
It seems that Test App with Test Users is unable to make books.rates calls until the main App is approved. The same api calls targeting a real App with a Test User works without problems.
As off right now i'm creating a post from my private account and on my
page. I'm trying to get the page it self to post the message i have
created. I been reading som documentation about page tokens. But
finding it difficult to find some eksampels. Does anyone of you guys
know the next step to getting to post messages as a page?? Would be
greatly thankful

What you need to post as a Page is a Page Access Token. Take a look at the Facebook docs about how to get it: https://developers.facebook.com/docs/facebook-login/access-tokens
Basically, you just call /me/accounts to get Access Tokens for all Pages and you use the particular Token to post instead of the User Token.
Here´s an article how to create an Extended Page Access Token without using the PHP SDK: http://www.devils-heaven.com/extended-page-access-tokens-curl/
I am creating Facebook application which get insights for user's page for multiple metric. Ex. for "page_active_users" and "page_active_users in one batch request.
I am using Facebook C# SDK. But not able to get data from Facebook insights (GraphAPI).
I used 5 different way to get the data but not succeed. By using Graph API method in browser shows data for a page but in batch request it returns empty array of data.
//type1
var para1 = new FacebookBatchParameter(HttpMethod.Get, "MyPageId/insights/")
{
Data = new { access_token = aToken, since = "2012-01-01", metric = "page_active_users" }
};
//type2
var para2 = new FacebookBatchParameter(HttpMethod.Get, "fql/", new
{
q = new[]{
"SELECT value,end_time FROM insights WHERE object_id=MyPageId AND metric='page_active_users' AND end_time=end_time_date('2012-01-01') AND period=86400"
}
}) { Data = new { access_token = aToken } };
//type 3
var para3 = new FacebookBatchParameter().Query(
"SELECT value,end_time FROM insights WHERE object_id=MyPageId AND metric='page_active_users' AND end_time=end_time_date('2012-01-01') AND period=86400");
//type 4
var para4 = new FacebookBatchParameter
{
Path = "MyPageId/insights/",
//Parameters = new {since = "2012-01-01"},
Data = new { access_token = aToken, since = "2012-01-01", metric = "page_active_users" },
HttpMethod = HttpMethod.Get
};
//type 5
var para5 = new FacebookBatchParameter
{
Path = "MyPageId/insights/page_active_users?since=2012-01-01",
//Parameters = new {since = "2012-01-01"},
Data = new { access_token = aToken },
HttpMethod = HttpMethod.Get
};
//Executed all above type by passing it to below method one by one.But always return empty data array while data is exists on Facebook which I tested using Grap API tool.
var result = client.Batch(para1-5);
Any help appreciated.
Thanks in advanced.

I found solution on my own. Hope this will help someone. Here is the solution.
///I created an enum for list of metrics that facebook is providing
public enum FacebookMatricType
{
page_active_users,
page_active_users_locale
}
//Created a list of Facebook batch request for each metric using LINQ to Object and //concatenate string using string.format method.
var batchParameters = (from FacebookMatricType matricType in Enum.GetValues(typeof (FacebookMatricType))
select new object[]
{
pPageAccessToken,"insights",matricType.ToString(),pFromDate.Date.ToString("yyyy-MM-dd"),pPageId
}
into objectParamter
select new FacebookBatchParameter
{
HttpMethod = HttpMethod.Get,
Path =
string.Format(
"https://graph.facebook.com/{0}/{1}/{2}?since={3}&access_token={4}",
objectParamter)
}).ToList();
//Once I get the list of request I execute it using facebook web client using C# SDK.
var facebookClient = new FacebookClient(pProfileAccessToken);
var results = facebookClient.Batch(batchParameters.ToArray());
//Results are ready to deserialize.
Thank you. ;)
